Description

TEMPRA thermal insulation Polyurethane foam boards are produced by VAPOTHERM HELLAS LTD (daughter company to Alfa Alfa Energy SA). The unique structure of TEMPRA PU boards, with uniform closed cells with sound walls, ensures a very low coefficient of thermal conductivity (λ = 0,024 Kcal / h m o C), hence superior thermal insulation result. TEMPRA PU boards show increased resistance to mechanical forces, high resistance to temperature variations from -15 °C to 110 °C, giving thus the opportunity to adhere by torching bituminous membranes directly on their surface. They are self-extinguishing. & show dimensional stability, resistance to chemicals agents (solvents, aces, etc.) and aging. TEMPRA PU boards can be produced with top/ bottom cover either with paper or high reflective aluminium foil. In the case of aluminium covers, a perfect vapor barrier is achieved , which gives the material longterm life-time efficiency.
